You would possibly guess the route values controller = House, action = Index could well be sufficient to crank out a URL utilizing site, and The end result would be /website?action=Index&controller=Household.

This is certainly Doing work high-quality. However, Let's say we desired to have extra specific routes? Say some thing like the following URLs:

A catch-all parameter may match routes improperly on account of a bug in routing. Apps impacted by this bug have the subsequent properties:
